  • Switched capacitor digital-to-analog converter
    Patent number: 9467162
    Abstract: A switched capacitor digital-to-analog converter (“DAC”) for converting a digital input code to an analog signal comprises a switched capacitor array and a reset switch having a first end and a second end. The digital input code is inputted to the switched capacitor array. The switched capacitor array is connected to a summation node. The first end of the reset switch is connected to the summation node and the second end of the reset switch is connected to a common mode voltage. The reset switch is closed after a plurality of sampling cycles. The analog signal is provided based on a summation voltage at the summation node.
